I tie on hook grub a CDC hackle as if I intended to tie the Mirage 2.
Keeping some tension in the hackle, wrap the thread around it. When I reach the length that I intend to give the body, I stop.
I go back, crossing the tying thread coils with those wrapped previously.
I cut the excess hackle.
I cut the tip of the hackle.
I tie a peacock herl next to the extended body.
I wrap the herl around the hook, tie it near the eye and cut it surplus.
Tie the head of fly
I take off the fly from vise and cut the CDC fibers of the tuft.
